Description

2,3-Dihydroxypropyl 2-Hydroxypropanoate is a versatile, multi-functional chemical intermediate prized for its unique combination of hydroxyl and ester functionalities. This compound is critical for formulators seeking to introduce hydrophilic character, modify solubility, or create reactive sites for further synthesis in advanced materials. It is particularly valuable for manufacturers in the pharmaceutical, personal care, and specialty polymer industries who require high-purity, consistent raw materials for sensitive applications.

Application

• Pharmaceutical Synthesis: Acts as a key intermediate or pro-drug linker in the development of active pharmaceutical ingredients (APIs), leveraging its ester and diol groups for controlled release or enhanced bioavailability.
• Personal Care & Cosmetics: Serves as a humectant, emollient, or solvent in high-performance skincare formulations, lotions, and creams, where its moisture-binding properties are highly valued.
• Polymer & Resin Modification: Used as a reactive diluent, cross-linking agent, or to impart hydrophilicity in the production of specialty polymers, coatings, and adhesives.
• Food & Flavor Industry: Employed as a solvent or carrier for flavors and food additives, where its generally recognized as safe (GRAS) potential profile is advantageous.
• Chemical Synthesis: Functions as a protected or activated form of glycerol and lactic acid derivatives in complex organic synthesis for research and fine chemical production.

Quality Control

Our 2,3-Dihydroxypropyl 2-Hydroxypropanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results from methods such as HPLC, GC, and titration are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen) after opening to maintain optimal quality and shelf life. Keep away from strong oxidizing agents.
